Check out this latest Jazz Blues Backing Track in E, and a quick lesson on Side Stepping.
As this is a Jazz Blues, there are a number of ii V I (2 5 1) turn arounds rather than the more standard V IV I V (5, 4, 1, 5) in the last 4 bars of a 12 bar blues before heading back to the 1.
Here are the chord progressions:
Section A:
E7 / A7 / E7 / E7
A7 / A7 / E7 / E7
F#m7 / B7 / E7 / F#m7 B7
Break:
E7 / Fdim7 / F#m7 / F#m7
G#m7b5 / G7 / F#m7 / F#m7
Section B:
E7 / F#m7 / G#7 / A#7
A7 / D#7 / E7 / E7
F#m7 / B7 / E7 / F#m7 B7
Here's the track:
Just start out with the E blues scale, or even E major or minor pentatonic at first. Then start experimenting with other scales and arpeggios when ready.
Try the Mixolydian scale over the 7 chords, and the natural minor over the minor 7 chords.
Try experimenting with the diminished or diminished dominant scale for the V chord - the B7. This scale is great as it has all the main tones of the V chord, in this case the B, D#, F#, and the A of the B7b chord, but also some tasty note choices eg - 13th (G#) and some more out there notes like the b2 (C).
Here's a quick lesson on sidestepping using this backing track. There's a tab to follow as well:
